PICKER CHECK FOR LOOMS.

Application inea May To all 'whom t 72mg/ concern.'

Beit known that I, Mic/Hann LANDi, a sub ject of the King ofItaly,'residing at Paterson, in the county of Passaic and State of NewJersey, have invented certain new and useful Improvements in PickerChecks for Looms, of which the following is a specification.

In box looms the picker for the shuttle usually slides on a rod at theback of the framing in which the boxes are guided vertically and whichforms a part of the rocking batten-including structure, and its inwardmovement is at present yieldingly checked by a buffer consisting of aleather strap which is folded zig-zag fashion and has its several foldspenetrated by the rod. This butter is quite unsatisfactory for thepurpose in hand because it soon increases in pliability upon being putinto use and is also affected by atmospheric conditions, 'so that atdifferent times it offers Widely varying degrees of resistance, whichresults in the blow of the picker being irregular in force and producesconsequent irregularities in the woven goods.

The object of this invention is to provide an attachment for box loomsfor yicldingly checking the picking motion of the picking medium whichshall oppose a substantially constant degree of resistance practicallyper-- manently and shall be simple 1n construction, readily attachableto any box loom, of enduring character, and capable of ready adjustmentas circumstances may require.

In the drawing,

Fig. l shows the right-hand end portion of a loom in rear elevation andwith my picker checking means attached thereto;

Fig. 2 is an outside elevation on a larger scale of said means and thepicker stick; and

Fig. 3 is a front elevation of said means.

In the loom frame a is arranged to rock back and forth the usualstructure including the batten b and the lay swords, only one of whichis shown at c, d representing the shaft, j ournaled in the frame,carrying the lay swords; said structure also includes the framing c inwhich the shuttle boxes f slide, g being the rod which carries the boxesand forms a part of the means for reciprocating them vertically. h isthe picker stick fulcrumed in a bracket z' projecting from the shaft d;it is normally held in the full line 192e. serial no. 639,051. l Y

position shown in Fig. l by the spring y', be-` ing adapted to have itspicking strokes im- 'z ing and horizontal rod which is secured to theframing in parallel relation thereto, m being the picker which slideson' the rod and in the usual way has an opening through which the pickerstick extends.

Bolted to the under side of the framing c near the lay .swords c is abracket n which projects rearwardly clear of thei framing. This brackethas an arm o which projects downwardly `and outwardly from the lay swordat an incline, having at its free end a forwardly projecting boss p fromwhich in turn projects a horizontal stud or pivot 29 which may beequipped with a cotter-pin g. Carried by the arm is a stop whichconsists of an elongated plate 1 arranged approximately horizontally andhaving its outer end s bent forward to form the stop proper. The

stop r is secured to the front face of the arm by a bolt t having aclamping nut u, the bolt penetrating a horizontal slot o in the stop, sothat the latter may be adjusted horizontally. The bracket yn hasupstanding therefrom at about the same pointfrom which the arm projectsdownwardly and outwardly an integral stop w which is bent outwardly andpreferably has its free end face arranged at a downward and outwardincline and equipped with an elastic buEer w.

Pivoted on the stud p, between the boss and the cotter pin, is a leverg/ upstanding from the pivot and having a forwardly projecting arm orlug e which preferably of movement of the picker stick h. The.

bracket lnf and the lever 'y have hooks n and y and these are connectedby a spiral spring 2, which normally acts to hold the arm bearingagainst the stop proper s.

When the device is in use, each time the picking means h m is impelledinwardly or made to perform the picking stroke the picker stick 7Limpinges against the rounded I face `a of theprojection a of lever y,the shoolibein'g'talien Lip by thespring e, which yieldingly resists theinward movement of the lever. lever is finally l definitely The inward'movement of -the limited by the ela?- ltic biier w, the @return movementof the picking means is assisted by the spring means 2 as the latterContractsv upony the 1n'.-

ward movement of the lever g/ being cheeked.

y for'the `purpose in hand, permits the arm and Consequently the bracketas a lWhole to be light in construction and yet strong enough to resistbreakage.

Another important feature oll invention `s the stop a which uponadjnstiient h'o'rizon'talljT varies the extent of throw of the lever to-the end that the .point of impact of Athe ,picking means ',.tlierewith1may be set outward Orfinvvardin the path oit travel of said means.

Having thus fully described my invention, What I claim as new. anddesire to seourefby Letters #Patent is In combination, with thehatten-including structure of a loom, a picking means movable thereininwardly and'"outwardly, a

bracketsecured vto said structure 'near lthe inward limit 'of motionvof's'aid lmeans and having an arm inclined downwardly and outwardly anda stop near the upper end 'of the arm, allever lulcrumed in the arm to'move 1n a plane parallel with the path oi movement of said meansagainst said stop 'and projecting upwardly from its itlerum intoith'epath ofsaid Emeans said bracket having near the lower end'o'lf the arman-- other Stop against lwhich the lever is adapt- 'f ed to fbea'r latan outward incline andA from which the lever 1s movable mwardlvlv and aspring extending` parallel and connected with the Iarm at -th'e lupperend thereof and with the levernear the lowverendoil thearnl and-normallyholding thelever against the stop.
